Wave-Driven Mixing Enhanced by Rotation in Red Giant Branch Stars
Simon Blouin, Paul R. Woodward, Pavel A. Denissenkov +2
Stars like our Sun expand as they exhaust their core hydrogen fuel, becoming red giants that eventually reach sizes up to 100 times their original radius. These giants have long pr…
Calcium Excess in Novae: Beyond Nuclear Physics Uncertainties
Mallory Loria, Pavel Denissenkov, Chris Ruiz +1
We examine Ca abundances in classical novae from spectroscopic observations spanning 65 years and investigate whether they are systematically high compared to those predicted by no…
Production of radioactive Na in core-collapse supernovae: the Ne-E(L) component in presolar grains and its possible consequences on supernova observations
M. Pignatari, S. Amari, P. Hoppe +8
Presolar graphite grains carry the isotopic signatures of their parent stars. A significant fraction of presolar graphites shows isotopic abundance anomalies relative to solar for…
Thallium-208: a beacon of in situ neutron capture nucleosynthesis
Nicole Vassh, Xilu Wang, Maude Lariviere +7
We demonstrate that the well-known 2.6 MeV gamma-ray emission line from thallium-208 could serve as a real-time indicator of astrophysical heavy element production, with both rapid…
NuGrid stellar data set I. Stellar yields from H to Bi for stars with metallicities Z = 0.02 and Z = 0.01
M. Pignatari, F. Herwig, R. Hirschi +16
We provide a set of stellar evolution and nucleosynthesis calculations that applies established physics assumptions simultaneously to low- and intermediate-mass and massive star mo…
